Hello, Cyrus IMAP uses the libxml2 function xmlNodeListGetString(). For empty XML elements this function returned NULL, but since version 2.13.0 it should return "" (empty string). Today the function was updated upstream to return again NULL, so 2.13.4 will include the fix. If you are using libxml2 after 2.13.0 then REPORT sync-collection (initial synchronization) principal-property-search (with empty <match/> element) might not work.
